Since 1985 a 10 year prevention programme aiming to reduce cardiovascular diseases (CVD) has been running in the county of Västerbotten in Northern Sweden.

The project started in Norsjö.

Thc prcsent investigation is a study on dietary intake, medical CVD risk factors and dental caries in five cross-sectional groups of 15-year-olds during 5 years (1987-1991) of the « Norsjö project ».

Most of the measured medical and dietary variables followed a similar trend, i.e. a positivc trcnd during the first 3 years (1987-1989) and in the last 2 years (1990-1991) the averages returned towards baseline values.

Dental caries prevalence followed a similar trend.

Parental educational level did not have a major influence on diet or medical CVD risk factors, but higher caries scores were noted in adolescents with parents with « low » education compared with adolescents where the parents had higher educational levels.

The results from the study also point to the fact that dental caries prevalence together with body mass index may indicate adolescents with CVD risk factors at unfavourable levels.

Dietary counselling by dental personnel to adolescents with high caries and moderate obesity can be of advantage in reducing caries risk, as well as risk for development of CVD at higher ages.
